It has been hypothesised that WTTSs are simply more evolved CTTSs with dissipated disks [1]}, [2]}. However, there are CTTSs and WTTSs that coexist [3]}, and their disk evolution is informed by their star-forming region and circumstellar environment [4]}, [5]}. The details of this complex evolution are beyond the scope of this study, however, the implication is that the amount of Li depletion (a known indicator of stellar age) is often higher in WTTSs than CTTSs, but cannot be assumed [6]}.
